Mechanically similar to the 5-series saloons and Karmann styled like the preceding 3.0CS/CSi, BMW's 6-Series coupé debuted in 1976 incorporating some components destined for the yet-to-be-announced 7-Series. The newcomer was similarly well specified, featuring all-independent suspension, four-wheel disc brakes and power-assisted steering as standard. Commencing with the 3.0-litre 630 and 3.3-litre 633, the range was supplemented in 1978 by the 3.5-litre 635, which would enjoy a production run lasting into the 1990s, being periodically up-dated in line with its sister models. Even today, some 30 years on, these big BMW coupés have enormous presence, and with a 0-60mph time of 7.8 seconds and a top speed of 134mph (633CSi) are not slow by any standards. With the 635CSi newly introduced and sales of the 633CSi slowing in the UK, BMW took the decision to upgrade the remaining cars in stock, the work being carried out at TWR's factory in Kidlington. The result was the limited edition 'Hallmark' model, which featured Alpina alloy wheels and front spoiler among various upgrades. It is believed that only 56 were produced (one for every BMW dealer at that time) all of which were right-hand drive. This limited edition 633CSi Hallmark model is finished in Alpine White with full red leather interior and has automatic transmission like almost every example produced, while other noteworthy features include power steering, air conditioning, electric sunroof and electric windows. 'GGJ 781T' has covered 75,000 miles from new and comes with a fully documented service history. The car has just been serviced, receiving new brakes, tyres, exhaust, etc and is described as in generally very good condition. 'On the button', it comes complete with its full original tool kit and book pack including service booklet and Hallmark supplement, and is offered with sundry invoices, MoT to April 2011 and Swansea V5. A lovely, unspoiled and original example of an appreciating asset.
