Faults:
AC compressor failed after roughly 1-2 months, replaced under warranty. Later replaced again under manufacturer recall.
Rear engine mount failed after roughly 6 months. Replaced under warranty. Has been fine ever since.
Seats were replaced a year ago due to extreme wear on the driver's seat next to the door. Replacement seats came out of a 92-95 Del Sol, which are constructed of different cloth. So far so good, but it did take years for the previous problem to develop, but the "new" seats are immaculate.
Currently in need of replacement suspension bushings on the driver's side (passenger side is showing signs of wear, while multiple bushings on the driver's side are actually torn), I believe primarily due to auto cross and track events. Taking freeway off-ramps at greater than recommended speeds couldn't have helped.
General Comments:
While better than the '96 Civic EX Coupe 5-speed I traded in for this, only a little of the '87 Civic CRX Si shines through in the Del Sol, which I had traded in on the Civic (just couldn't live with the mushy EX suspension).
It is a very heavy car for it's size, which deters from handling and straight-line performance. That it does as well as it does in the twists seems very remarkable to me.
While a very fun car to drive in stock form, when shod with summer-only tires the thing handles like it's on rails. With minor suspension modifications it reached >1G on the skid pad. In combination with stock disc's & calipers, it was no longer possible to lock the tires in a straight line (n corners you can, with effort, get the tail to wag in a very controlled fashion).
Winter has proven equally a blast, when the summer tires are transplanted with 185/65R14 Winter-only tires. While I initially tried out Blizzaks, their 75% uber-soft tread compound left me buying a new set of tires after 1 year due to warm Chicago winters. Traditional snow tires have lasted multiple years and provided reasonable dry performance and very good snow & ice performance for the few days a year when I need it.
The added weight the Del Sol gained by lopping off the roof seems to have helped it dig into the snow during winter months. This is literally the best handling winter car I've ever driven, and I grew up in Detroit in a family who worked for the Big 3. And remember - an SUV is not a car.
