Specs side by side
What owners say
Allante
Overall
Sentiment is sharply divided and heavily dependent on model year and powertrain. The vehicle is widely recognized as a unique, stylish, and historically significant two-seat convertible that has developed a niche following for its "retro futuristic" Pininfarina design and conversation-piece status. However, long-term owner reports are dominated by criticism of fundamental flaws.
Best version to buy
Insufficient owner data available to declare a consensus "best" version. Discussions indicate a split: some owners seeking reliability advise seeking a pre-1993 model with the non-Northstar 4.5L V8 to avoid the notorious head gasket issues, while others express a preference for the increased power of the 1993 Northstar V8 despite its reliability risks.
Known issues
- ⚠Head gasket failure (Northstar V8): severe, well-documented issue requiring engine removal, block re-threading, and upgraded head studs; typically occurs around 80,000-120,000 miles. Frequency: very frequent.
- ⚠General powertrain unreliability: early HT4100 V8 noted for poor longevity and lack of power; later 4.5L V8 considered more reliable but still a concern in a 30+ year old vehicle. Frequency: very frequent.
- ⚠Digital instrument cluster failure: complete failure of gauges and instruments is a known, common point of failure; parts are difficult and expensive to source. Frequency: recurrent.
Corvette
Overall
Owner sentiment is mixed and heavily dependent on generation and specific model. The C6 generation (2005-2013) is frequently discussed, with owners appreciating its performance value and LS-based engine reliability, but reporting recurrent electrical and fuel system issues, particularly in higher-mileage examples. The C7 generation (2014-2019) is noted for its performance capabilities, though isolated reports mention specific mechanical problems requiring significant repair.
Best version to buy
Insufficient owner data available to declare a consensus "best" version. The C6 Z06 and Grand Sport are mentioned positively for their performance.
Known issues
- ⚠Electrical system malfunctions (C6): erratic gauge behavior (fuel, battery), RPM fluctuation, intermittent power loss. Frequency: recurrent.
- ⚠Fuel system leaks (C6, C4): strong fuel smell, particularly when tank is full; attributed to cracked plastic fittings on top of the fuel tank. Frequency: recurrent.
- ⚠Slow or problematic startup (C7): sputtering during hot starts, remote start failures, potentially linked to a Fuel Pump Control Module. Frequency: isolated.
