The TDI Beetle has some nice characteristics to it like great fuel economy, reasonable amount of torque produced from the 1.9L engine, and overall fun to drive.
The down side is the car is almost completely plastic. So expect thing to randomly break apart on it. These cars is riddled with electrical problems that doom every VW owner to spend massive amounts of time and money at repair shops.
unless you have plenty of money, time, and want to become a good friend of your local VW/Audi Tech avoid this car like it was an ex-spouse with the plague.
