Always the consummate professionals, Amir, Rueben, Andrew and the team at Avus go the extra mile to make sure that my old E39 M5 is dialled in like no other!! It's the best 4 door saloon car ever made. EVER!! On the streets or hooning it up at various race tracks, Avus has made me confident that the car will be solid and perform at her best!!!!Thanks, lads.
