I bet you're surprised at some of the answers!
If there was Alfa history, you'd think the dealer would retrieve it....
Contacting the previous owner is a good idea, I expected that when we traded the 147, didn't happen, maybe they liked all the reciepts. Its only a phone call and what could go wrong?
If the price is right, it could be a very good buy. I'd either get a bit knocked off for the work, or get the dealer to do all the work and see the bits they take off.
There must be some kind of warranty, it always total protection, but it helps. Make sure you see the Ts & Cs first. You may have to get the work done by the supplying dealer.
If we assume they do the work to your satisfaction and the price is right, I'd buy it and then get your Indy to have a good look at it, then claim anything you can on the warranty!
Even if it costs a few quid to get it looked over, its good for peace of mind.
The lack of history is only a disaster if you only intend to keep it for a year or two, if its a long term buy, then your care and attention will negate this.
