Turbos still has a certain appeal which is why I'm trying to keep my Laser within the family. I rather sign it over free to a relative than sell it to a stranger.
Anyway, a turbocharged engine is as valid as a N/A or supercharged engine. So long as people know what it means to own a turbo car then, there's no problem. Since most turbo car owners tend to be enthusiasts, maintenance costs are well...... irrelevant is the wrong word. Bah. it's too early in the morning to think......
Right now, if I was still single and lived in an apartment or condo, I'd probably have a turbo car of some sort in the parking lot. That turbocharged Pontiac Solstice looks mighty appealing. Also, I still long for a GMC Syclone. If I can find one in good shape.

Add: Subaru's probably the only company that have turbocharged cars right with its 2.5L turbo 4.
2.5L is pretty big for a 4-cylinder. Most other turbocharged cars have 2.0L or less. Maybe that extra 0.5L makes a difference.
