I bought my Del Sol SI and drove it about 30,000 miles the first year. It's just so much fun, top on or off. It really loves the higher RPMs. For the performance it gives, the low emissions and high gas mileage (32mpg) are fantastic. It's been extremely dependable, and to keep it that way I feed it good quality regular gasoline and keep up on service. While it is a little car, it's got a huge trunk. I've taken it camping several times on back country & mountain trips. It's the perfect commuter car (in lieu of a hybrid). A little secret that it took me 8 years to discover is that many carwashes will give a discount on washes and waxes due to the car's small size.
The removable top is really cool, but I think I love the automatic roll-down rear window even more.
The bucket seats have no lumbar support. Also, with legs out in front, it's natural to sit on your tailbone.
