   Phil is absolutely correct (as usual)! Our local Audi dealer spent
$50,000 on a computerized laser alignment machine specifically to service
A4's. This was a requirement before Audi would let them offer A4's for sale.
Boy, you should see those mechanics on a keyboard (painfuuullll!)
    As an aside, the mechanic told me he wouldn't buy a new A4. Said the
aluminium suspension components didn't stand up to curb impacts and cost a
fortune to replace!
