Classics.
You try buying parts for a Minor or a Mini then. Most halfords kids have never even heard of a Morris Minor. They usually ask who its made by, refusing to accept 'Morris' were a real company.
The other fun game with minis is asking for a jump start or a new battery. Poor fuckers looking under the bonnet thinking the electrics must run by magic.
And, lastly, if you want to really stun your local Ford Parts Dept... ask them for some XR2 parts. Baring in mind its one of their own cars. The look of puzzlement is a proper joy. Anything older than a mk5 and theyve never heard of it.
