The scissor lift is from Automotech Services Ltd and is an AS-7630 (or was when I bought it). Their website is:
www.automotechservices.co.uk
The lift I have is capable of lifting 2.7 tons although I have not had the nerve to test it with my Range Rover and was £995 + VAT at the time. Overall it has proven very good although you do need to watch the center of balance (if that is the correct term) as it moves as the scissors raise - I have since turned the lift around from the way it is in the photo which is a lot better for a rear / mid engined car. Oh and its also bloody heavy.
At the time there were slightly cheaper products out there - direct imports from china, ebay, etc. but this one was rated to a higher capacity and there was someone at the end of the phone who knew about the product, how it worked and was able to supply spares if required. Anyway have a look at their website and make your own mind up - they supply all different types of lift.
If you have any questions let me know, hope this helped.
