1997 Chevy Suburban 4x (18mpg hwy 12 city), almost 200k and going strong. Got rid of my brand new 2008 truck when the registration here is CA was $700 for 1 year!
Also have a 2003 Buick Le Sabre (25mpg hwy).
I love driving new cars. We used to buy new almost every year. Now I love driving reliable and paid for!
And registrations are $80 & $97. It goes according to how much you paid for the vehicle.
I would have to save an AWFUL LOT of gas to make up for purchase price/ registration on a new car. In my calculations, I may never realize enough gas savings to make a difference on that front.
I do plan on getting something newer in a couple of years. I want to/will get a 3/4 ton, Chevy, crew cab, long bed, 4x4 (maybe with a 454) and not dually. Yes, I am a Chevy girl (used to have a 2001 Corvette zo6), and I like trucks because they are so useful. Safety is a bonus, it's not usually the trucks that are crunched in crashes.
I also got my motorcycle license, but haven't pursued that at all. Too many distracted drivers.
