Gallery: Take a closer look at Mohammed's classic Pontiac Trans Am and Cadillac Eldorado!

When Mohammed sold his 1989 560SL, he started looking for another classic to tinker with, but like the buses, two came along! And, they’re two of the best anyone could wish for!

Large personal luxury coupes have all but faded from existence, which we think you'll agree is a shame once you take in all 226 inches of this 1978 Cadillac Eldorado Biarritz.

The 1978 model year was the last for this majestic Cadillac land yacht...

The next generation model's wheelbase and overall dimensions would shrink significantly...

It has so many bells and whistles - including a tiny compass on the driver's side view mirror. How cool is that?!

This survivor of the Malaise Era of the Seventies looks like it is brand new.

Check out those seats! They're more comfortable than the sofas in most living rooms!

A new grille was the only major change for 1978; the Eldorado would be completely redesigned and downsized for 1979.

Power from a 7.0-litre V8 routed to the front wheels through a three-speed automatic transmission.

If you're a Pontiac fan and you like Trans-Ams, then you've gotta love these Turbo Pace Cars.

It's great appearance and small production run of only 5,700 units is what makes these collectible and desirable.

This Trans Am was built at the Norwood, Ohio plant and rocks the Indianapolis 500 Pace Car decals.

The options include: 4.9-litre 301 cubic-inch Turbocharged V8 engine.

Mated to a 3-Speed automatic transmission and featuring a positraction rear axle with 3.08:1 axle ratio, it produced around 200bhp which was plenty for the performance-strangled early Eighties muscle cars.

Options included the WS6 performance handling package with 4-wheel disc brakes and best of all, T-tops!

It also got a specific oyster interior with hobnail cloth inserts in doeskin vinyl with Firebirds logo embroidered into rear seat back.

It also got a leather stitched formula steering wheel with unique horn button and the classic Trans Am turned-aluminium dash

The 301 cubic inch V8 sported a first-time feature for the Firebird line, a turbocharger. Seeing one of these beauties driving down the road would make anyone's day!

How cool are those white painted turbo cast aluminium wheels!

Faced with demands for improved fuel economy, lower emissions, and reduced insurance claim costs, car makers scrambled to build cleaner and more efficient cars. The Trans Am may have lost power but it still looked fast thanks to all of the scoops and spoilers on the body.
