Previous reviewer nailed it. Engine fires were limited to the 84 and in subsequent years the issue was moot, though the bad rep stayed with it till the end. Had overheating problems which were fixed by adding a 190 thermostat, down from the 220 originally used.
From my perspective, while one damn fine looking car, the 84 was severely underpowered, given its "sports car" designation. Later years GM increased horsepower though never to the point were serious drivers would consider it worthy, until the 88. By then though, sales had slumped due to the decline in two-seaters and the previous issues which, as I said, plagued the car despite of the fact that they had been dealt with.
The prototype 89-90 was rumored to be faster, with better handling, braking, and cheaper than the Corvette, though I seriously doubt it would have replaced the Corvette as GM's flagship sports car. If GM execs had any sack, they'd reintroduce it.
Lack of space is a non issue. It's a two seat sports car. You want storage, by a Freightliner with trailer.
