Know there's quite a few on here who are pretty decent with cars so just a cry for help from someone pretty useless.

Been to change cars for quite a while and one has popped up that ticks the boxes except..

It's been garaged for about 4 years as it was someones who passed away and they hadn't done anything with it. They have the v5 and all paperwork, obv would do a hpi so that side all seems fairly straightforward

It's having a full service and new mot. having brakes stripped and greased, a few needly thngs that are needed to go through the mot. They say no unexpected noises etc.

Is it mad to buy a car stood round this long and what are the likely pitfalls / things to look for?
