Actually, that's not a bad idea.
Think how many owners I could frighten in to a new set of tires, "$1,200 out the door Madam - just so much cheaper than possibly wrecking your eight thousand dollar transmission with uneven tires. Would you like a winter set too for $3,000 - special mid-summer offer you know?"
Next up? A new set of rotors and pads all round - "Just $1,600 on the card, Sir".
"That clunk? It's a new valve chest - a mere $2,000 to you my friend".
Oh, and whoopee dipetty doodah, the drive shafts - the DRIVE SHAFTS!! I'm actually dribbling at the keyboard at just how many of those I could poke down folks' throats . . .
"Do you really your good lady to break down on the side of the freeway, Sir? Just sign up right here for another fifteen hundred bucks. Thank you."
Oops, I nearly forgot the manifold arms " Yes of course you need new manifolds for two grand. Come back tomorrow afternoon, Sir" [after I've fitted the eighty buck Gruvenparts arms!!].
