The Opel Manta, a stylish coupe produced by Opel from 1970 to 1988, holds a special place in automotive history. Understanding which model years offer the best blend of performance, reliability, and desirability is crucial for potential buyers and enthusiasts alike. This guide aims to provide a comprehensive overview of the Opel Manta's production run, highlighting the best years and those that might present more challenges.

Opel Manta Model Year Overview

Model Year Range Key Features & Improvements Potential Issues & Considerations
1970-1975 (Manta A) Distinctive Coke-bottle styling, available with 1.6L or 1.9L engines, relatively simple mechanicals, good parts availability. Rust can be a significant issue, particularly in sills, floors, and wheel arches. Early models may have less refined interior features. Carburetor tuning can be tricky on some models.
1975-1988 (Manta B) More modern styling, wider range of engines (1.2L, 1.3L, 1.6L, 1.8L, 2.0L), improved interior, updated suspension, fuel injection introduced later in the production run, GTE and GSi performance models. Rust remains a concern, especially in the later years. Some engine variants are less powerful than others. Finding specific trim parts for rare models can be difficult. Electrics can be problematic in later models.
1982-1988 (Post-Facelift Manta B) Revised front end, improved aerodynamics, updated interior, often featured fuel injection, enhanced performance. Rust remains the primary concern. Later models can be more expensive to maintain due to more complex systems. Finding good examples can be challenging.

Detailed Explanations

1970-1975 (Manta A): The Manta A marked Opel's entry into the sporty coupe market. Its distinctive "Coke-bottle" styling and relatively simple mechanicals made it an appealing and accessible car. The available 1.6L and 1.9L engines provided adequate performance for the era. Parts availability is generally good due to the Manta A's popularity and the interchangeability of components with other Opel models. Rust is the most significant concern for Manta A models, and thorough inspection is essential before purchasing.

1975-1988 (Manta B): The Manta B brought a more modern and angular design to the lineup. A wider range of engines was offered, catering to different performance preferences. The interior was also updated, providing a more comfortable and contemporary driving experience. The introduction of fuel injection on some models improved performance and fuel efficiency. While offering more advanced features, the Manta B is still susceptible to rust, and potential buyers should carefully inspect the bodywork.

1982-1988 (Post-Facelift Manta B): The facelifted Manta B featured a revised front end, improved aerodynamics, and an updated interior. These models often incorporated fuel injection, leading to enhanced performance and fuel economy. The later Manta B models are generally considered more desirable due to their improved features and performance. However, finding well-maintained examples can be challenging, and rust remains a critical factor to consider.

Best Years to Consider

Several model years stand out as particularly desirable within the Opel Manta range:

  • 1974-1975 Manta A: These later Manta A models benefited from minor improvements and refinements throughout the production run. They offer a classic Manta experience with relatively simple mechanicals and decent parts availability.

  • 1984-1988 Manta B GTE/GSi: The GTE and GSi models represent the pinnacle of Manta performance. These fuel-injected variants offer a significant power boost and a more engaging driving experience. They are highly sought after by collectors and enthusiasts. Finding one in good condition is key.

  • 1982-1988 Manta B (Fuel Injected): Any Manta B model with fuel injection, even if not a GTE/GSi, offers a significant advantage in terms of performance and reliability compared to carbureted versions. These models generally provide a more refined and enjoyable driving experience.

Years to Potentially Avoid (or Approach with Caution)

While all Opel Mantas have their charm, some model years may present more challenges:

  • Early Manta A Models (1970-1972): These early models may have less refined interior features and potentially more rudimentary mechanicals compared to later Manta A versions. Rust is still a major concern.

  • Manta B Models with Smaller Engines (1.2L, 1.3L, 1.6L): While these engines are reliable, they may not provide the performance expected from a sporty coupe. They can feel underpowered, particularly in later, heavier Manta B models.

  • Mantas with Significant Rust Damage: Regardless of the model year, any Manta with extensive rust damage should be approached with extreme caution. Rust repair can be costly and time-consuming, potentially exceeding the value of the car. A thorough inspection is essential.

Specific Engine Considerations

The engine is a crucial factor in the overall Manta experience. Here's a breakdown of the most common engines:

  • 1.6L and 1.9L (Manta A): These engines are reliable and offer decent performance for their time. The 1.9L is generally preferred for its increased power output. Carburetor tuning can be a challenge on some models.

  • 1.2L, 1.3L, 1.6L (Manta B): These smaller engines are generally reliable but may feel underpowered, especially in later Manta B models. They are best suited for economy-minded drivers.

  • 1.8L (Manta B): The 1.8L engine offers a good balance of performance and fuel economy. It's a popular choice for those seeking a more engaging driving experience without sacrificing efficiency.

  • 2.0L (Manta B GTE/GSi): The 2.0L fuel-injected engine is the most powerful option available in the Manta B. It provides excellent performance and is highly desirable among enthusiasts. These models are often more expensive to maintain.

Rust: The Ever-Present Threat

Rust is the single biggest concern when buying an Opel Manta. These cars were not known for their rustproofing, and many examples have succumbed to corrosion over the years.

  • Common Rust Areas: Pay close attention to the sills, floors, wheel arches, door bottoms, and areas around the windshield and rear window.

  • Hidden Rust: Rust can also hide in less obvious areas, such as behind trim panels, under the battery tray, and in the engine bay.

  • Professional Inspection: If you are not experienced in identifying rust, it's highly recommended to have a professional mechanic or body shop inspect the car before you buy it.

  • Repair Costs: Rust repair can be expensive, so factor this into your budget when considering a Manta.

Key Features to Look For

Beyond the model year, several key features can significantly impact the value and desirability of an Opel Manta:

  • Fuel Injection: Fuel injection offers improved performance, fuel economy, and reliability compared to carbureted models.

  • GTE/GSi Trim: The GTE and GSi models are the performance variants of the Manta B, featuring more powerful engines, sportier suspension, and unique styling cues.

  • Original Condition: Mantas in original, unmolested condition are generally more valuable and desirable than those that have been heavily modified.

  • Complete Documentation: Service records and original paperwork can add value to a Manta and provide valuable insights into its history.

Factors Influencing Value

Several factors influence the value of an Opel Manta:

  • Model Year: Later models, particularly the GTE/GSi variants, generally command higher prices.
  • Condition: Excellent condition examples are worth significantly more than those with rust or mechanical issues.
  • Originality: Original, unmolested cars are more valuable than heavily modified ones.
  • Rarity: Rare models or those with specific options may be worth more to collectors.
  • Location: The market for classic cars can vary depending on location.
