I consider myself a car nut, but have nothing in the stable that reflects that. Our daily driver (wife and I commute together, along with kiddo transport) is a 2006 Chevrolet Impala 3LT. We probably should have got a minivan, or maybe an SUV, but couldn't shake the associated stereotypes. The funny thing is, we figured we wouldn't need that much space 95% of the time (turned out to actually be more like 75% of the time) and thought we'd enjoy the gas savings of another sedan.
I've always had good luck with GM cars, and I know them very well. We had a '97 Olds Cutlass previously that we clocked 198,000 miles on, and it still looked great too. We had only about $2000 in repairs into it, over the 8 years we owned it. It really just needed a new A/C compressor.
We ended up with an Impala 3LT simply because I really wanted: remote start, the 3.9L (240HP / 240ft.lbs. torque), axle-back dual exhaust, and the 17" wheels. It's not the best handling car in the world, but it's fair for a family sedan. It's fast though... much faster than anything else I've owned. It's 100% stock and likely always will be; might toss some aftermarket mufflers on it, but it always sounds pretty raunchy for a V6.
My vehicle is a 2001 Silverado Z71 4x4 Extended cab. 5.3L V8 (285HP / 325ft.lbs. torque), 3.73 gears and otherwise plain jane stock. I'd really like to do a 3" lift, some bigger tires, and put an exhaust system on it. GM trucks are much too quiet from the factory; too low as well, for that matter.
Right now, I'm longing for an early 70's Camaro RS (aka. split bumper). That's recently trumped my life long desire to own a '69 Camaro, but that doesn't seem as practical as it once was (availability and cost.) I'd take a '68 GTO or Chevelle in a heartbeat though. I've been waiting so long that I may aim for an '86-'88 Monte Carlo SS; they're cheap and they're a good platform to build on. They've been going up in value recently too. At the same time, I wouldn't mind building a trail rig either. We have some pretty good trails around here, not to mention some dunes open to ORVs.
