Hi Steve

Have you thought of installing one of those electric car lifts.............. think the retail is about £1600 / £1800 and they come to you in kit form and they just bolt to the floor.................. I am sure someone will have seen them advertised

they are generally advertised in the car mags.................... might save lots of back ache and crawling on your hands and knees (my knees are goosed !)

Cheers

Phil
