Detailed Explanations
Engine (1988-1989: 3.8L LN3 V6): The initial Reatta models featured the 3.8-liter LN3 V6 engine. This engine, while reliable for its time, produced around 165 horsepower. It's known for its smooth operation, but it can suffer from common issues like intake manifold leaks and sensor failures, typical of engines of that era.
Engine (1990-1991: 3.8L L27 V6): From 1990 onwards, the Reatta received the upgraded 3.8-liter L27 V6 engine. This version offered increased horsepower (around 170) and torque, resulting in slightly improved performance. It also benefited from some refinements that enhanced its overall reliability compared to the LN3.
Transmission (1988-1989: 4T60 4-speed automatic): The 4T60 transmission was a common choice for front-wheel-drive GM vehicles of the time. While generally dependable, it can experience issues like slipping or hard shifting, especially with age and lack of proper maintenance. Fluid changes are crucial for its longevity.
Transmission (1990-1991: 4T60-E 4-speed automatic): The 4T60-E transmission represented an electronic update to the earlier 4T60. This electronic control allowed for smoother shifts and potentially better fuel economy. The "E" version also generally improved reliability compared to its predecessor.
Instrument Panel (1988-1989: Touchscreen CRT): One of the most distinctive features of the early Reatta was its touchscreen CRT (Cathode Ray Tube) display. This system controlled various functions, including the radio, climate control, and trip computer. While innovative for its time, these CRT screens are prone to failure, often becoming dim or completely inoperable. Repairing or replacing them can be challenging and expensive. This is a major consideration for potential buyers of 1988-1989 models.
Instrument Panel (1990-1991: Traditional Gauges): Recognizing the reliability issues with the touchscreen CRT, Buick replaced it with a more conventional gauge cluster in 1990. This included analog gauges for speed, RPM, fuel level, and temperature, along with digital displays for other information. This change significantly improved the car's overall reliability and user experience.
Brakes (1988-1989: Teves Mark II ABS): The Teves Mark II anti-lock braking system (ABS) was used on the early Reatta models. While it provided enhanced braking performance in slippery conditions, it's known for its complexity and potential for malfunction. Repairs can be costly, and finding replacement parts can be difficult.
Brakes (1990-1991: Teves Mark IV ABS): The Teves Mark IV ABS system, introduced in 1990, was a more refined and reliable version of the earlier system. It offered improved performance and fewer potential issues compared to the Mark II. This is a significant advantage for the later Reatta models.
Convertible Availability (1990-1991 Only): The convertible version of the Reatta was only available in the 1990 and 1991 model years. This makes these years particularly desirable for those seeking an open-top experience. The convertibles featured a power-operated top and reinforced chassis to maintain structural rigidity.
Cosmetic Updates (1990-1991): Minor changes to badging and interior trim: While the overall design remained consistent, the 1990-1991 Reatta models received subtle cosmetic updates. These included minor changes to the badging, interior trim, and seat upholstery. These changes were relatively minor but contributed to a slightly more modern appearance.
Reliability (1988-1989: Generally good, but early CRT issues): The early Reatta models are generally considered reliable, especially considering their age. However, the touchscreen CRT is a significant potential source of problems. Other common issues include vacuum leaks, sensor failures, and typical wear-and-tear items.
Reliability (1990-1991: Improved engine and ABS reliability): The later Reatta models benefited from improvements to the engine, transmission, and ABS system. These enhancements resulted in improved overall reliability compared to the earlier models. The elimination of the touchscreen CRT further contributed to a more dependable driving experience.
Collectibility (1988 models have some collector interest due to being the first year): The 1988 Reatta models hold some collector interest due to being the first year of production. However, the touchscreen CRT and other early production quirks can detract from their overall desirability.
Collectibility (Convertibles generally more desirable; Final year (1991) sought after for improvements): Reatta convertibles are generally more sought after by collectors due to their rarity and open-top design. The 1991 models, being the final year of production, are also desirable due to the cumulative improvements made over the production run.
Frequently Asked Questions
Which Reatta year is the most reliable? The 1990 and 1991 models are generally considered the most reliable due to the upgraded engine, transmission, and ABS system, and the replacement of the problematic touchscreen CRT with traditional gauges.
Are Reatta parts difficult to find? Some parts can be challenging to find, especially those specific to the Reatta. However, many components are shared with other GM vehicles of the era, making them more readily available.
Is the Reatta a good investment? The Reatta can be a good investment for car enthusiasts, particularly well-maintained convertibles and final-year models. However, they require careful maintenance and shouldn't be viewed as a quick way to make money.
What are the most common Reatta problems? Common problems include issues with the touchscreen CRT (1988-1989), ABS malfunctions, vacuum leaks, and general wear-and-tear associated with older vehicles.
How much does a Buick Reatta cost? Prices vary widely depending on condition, mileage, and model year. Expect to pay anywhere from $3,000 for a rough example to over $15,000 for a pristine convertible.
Conclusion
The Buick Reatta offers a unique blend of luxury and sporty styling.
