Understood, but if you care about the kind of car, then you shouldn't book the Lock Low and Go. It's like gambling in Vegas: you win some, you lose some (only unlike Vegas, you save money in the process). You sorta lose your right to complain when you book it.
And if you ignore what they look like on the outside, from inside, the PTs aren't half bad...(they're not half good, either, but...).
