I sold my street bike because the only time I was having fun was when I was doing something illegal. Also sucks monkey balls in the summer wearing all the gear in the heat while in traffic.
I always thought blowing a shit ton of money on a vehicle was stupid, that frame of thought came from a poor student. Now with a decent job, I have the ability to spend a little money on my "wants".
It's slow and old. But it's kind of unique. It's fun to tinker on. Now, as per the why GT3's suck, and shitty cars are the shit thread. I drive my cars slow and they feel fast and fun
I don't get excited when I see an exotic anymore because I see one(or 5) daily. It's lost that wow factor. I guess you are correct that's lost a little bit of interest in cars since having ridden 170hp bikes, even though i've never really been in a crazy fast street car. I now am more interested in the work/craftsmanship that goes into a vehicle then the amount of money you can spend on one.
I think I need a dirt bike again. Adrenaline rush that won't get you a ticket, won't cost you an arm and a leg either.
