before you think of getting a PT cruiser..... (BTW Dollar has them)
Look at how much trunk space they DON'T have.......
If it's just you and your son then it will be ok.
If you have three or four people and luggage...IMHO..forget it...
We rented from Dollar with two adults, two kids, two large suitcases and four carryons. They tried to give us a cruiser. Only one of our 29" suitcase would fit in the back area. We couldn't figure out where to put the rest without collapsing the rear seat. We made them give us another vehicle. As we were loading up our replacement...we saw them trying to give the same car to a family with 5 (two in carseats)..... They didn't fit either....
PT cruisers should almost be in the compact vehicle catagory.....
