My wife thinks I'm having a midlife crisis because I want to buy a sports car - I'm really intrigued by the Subaru BRZ even though there is no room for hauling bikes.
I've had my truck for 10 years and at the rate I'm going, I'll have it another 10 years before it dies. I don't really have a good reason to get rid of it, and I am much too and practical to trade in a perfectly good, and paid off, truck for something that requires car payments.
What I really want is a second car that I can take out on weekends and for fun but still drive the truck regularly. I briefly considered getting an older Porsche, but a buddy of mine who restores old Porsches said it would be a money pit. And my wife really hates the idea of a third car as it would mean her car would have to be in the driveway instead of the garage. (My truck is already parked in the driveway - we need a place for bikes and stuff.)
