Which used Chrysler PT Cruiser estate should I buy?
Spec-wise, go for a Touring model, which will come with all the kit you'll need fitted as standard.
Likewise, there's really only one engine choice - diesel. The first one, a Mercedes-Benz unit, was introduced into the PT Cruiser line-up in 2002, and is a far better bet than the early 2.0-litre, 140bhp petrol that was phased out in October 2004. True, the petrol may be swifter in a straight line, but the more economical diesel pulls much more strongly from low revs. However, by modern standards, refinement isn't great.
But, if your budget stretches, go for the common-rail 2.2 diesel unit that was introduced when the PT Cruiser was given a face-lift in 2005. It produces more power - up from 119bhp to 150bhp - and refinement is also significantly improved.
Private sales are a good place to look for a bargain, but don't forget Chrysler dealers: many also keep a wide range of used stock.
