Need some information here, although I'm researching on the web...

There is a neighbor selling his 2004 Maserati Spyder. It's in great shape. He just told me that if I give him $22K he will sell it to me. I looked online and prices are in the high 20's to mid 30's depending on condition and mileage. His Maserati has 38K miles on it.

I don't know anything about Maseratis. Any feedback? Are they expensive to maintain? What about finding shops that can work on it if needed?
I'm also looking at insurance cost.

Comments or suggestions?
