Ferrari F355

Probably the first Ferrari in Mauritius & the most popular one in its time as a record 11,273 units were produced. A 1994 model, which even Jeremy Clarkson described as:

The Ferrari 355 is like a quail’s egg dipped in celery salt and served in Julia Roberts’ belly button.

The 355 is very probably the best Ferrari of all time… & of course, if it’s the best Ferrari of all time, it’s just got to be the greatest car… in the world.. ever!

& I've got one at home... I mean a reduced-size model. ;)

Ferrari F430

The current top-selling sportscar from Ferrari. Launched in 2005, it’s a typical performance car - short, nimble & very fast. A comparison would be with the Lamborghini Gallardo. Also exists in Spyder version & the lightweight stripped-down 430 Scuderia.

Ferrari F430 is "just about the best car I've ever driven" – Jeremy Clarkson

Ferrari 612 Scaglietti

The family car… xD Yeah, the only 2-door Ferrari coupé with 2 back seats large enough for someone to actually sit on them. Not exactly a stunner, but it’s probably one of the most tame Ferrari. Production started in 2004.

… the most "astonishing" car made that year (2005) – Jeremy Clarkson

Ferrari 599 GTB Fiorano 

Supercar of the Year 2006 by Top Gear Magazine. The 599 is not only a sheer piece of beauty (you can spend the whole day drooling at it) but is the most powerful beast let out by Ferrari as a mass production car. As expected, Jeremy Clarkson describes it best…

Because, as a piece of automotive engineering, the 599 is biblically, stratospherically, crushingly brilliant. Even at normal speeds on normal roads you know that you’re in a thoroughbred. You can feel it straining. You can hear it working. You know that if by some miracle you are presented with a piece of road which is wide and open and free from Rovers and speed cameras, it would deliver a hammer blow big enough to knock down the doors of Fort Knox.

It accelerates with a savagery known only to silly mid-engined supercars or plastic bathtubs from Caterham. It rides on its tall tyres with a composure that’s almost diplomatic in its smoothness. And believe me on this: it looks a trillion times better in the flesh than it does in the pictures. It’s not pretty but it has the brooding presence of a mafia hitman.

This is by far the BEST SUPERCAR in Mauritius. Well, not anymore (check below)...

So we have practically all current Ferrari models in Mauritius (Ferrari California isn't for sale yet & the Enzo is well…). Add the Porsches, the Aston Martins, the Audi R8 & the 2 Godzillas (Nissan GT-Rs), we have a impressive lineup of supercars in Mauritius. The only one missing is a Lamborghini... (See below)

You can check live pics of the supercars on LeConceptCar.com Forum. :)
