I have done both so far.
To be honest there is just as much money wrapped up in Bikes as there are in Cars if you plan on grudging atleast. Hell I was looking at a laundry list of parts and what not for the bike. I already have so much invested in one car I really don't plan on dumping anymore into it. I really enjoy my new DD. It has power, comfort, and good looks. The whole time I was on my bike and what not I had a blast but those will admit you do miss cars alot doing it. I won't ever get out of riding, I am in the process of locating a new two wheel beast to throw in my inventory. Bikes = Cars.. to me atleast. Can't wait to see all you fools out this summer for some good old fun!
