All ZT's where victims of project drive mate (see my buyers guide) so whernt as well spec'd as a 75 usually, but most if not all can be retrofitted.
My advice, buy a 115 model over the 131 as it will save you on insurance and you will want to upgrade it anyways down the line with the ron boxs and such.
Go for a car with projectors or xenons over the halogen units as they are hard to source and difficult to upgrade.
Also, try and go for a SE if you can. Theres the entry, entry plus, and SE models, they usually have a sunroof and cruise control.
99% of them wont have full leather or electric seats, again where an SE is a bonus.
Again a very popular car for towing with, but that can mean more wear and tear and so on, so a car without a towbar doesnt mean it hasnt been used for towing at some stage etc.
I spied this locally also....
