Description
For sale is a 1988 Maserati Biturbo Si, originally sold new in Sweden and acquired by me here in Norway in the summer of 2021 from its previous Swedish owner, who had owned the car for 12 years.
This is a truly magnificent grand touring machine, combining exceptional comfort with genuine sporting character. Everything electrical works as it should, including the digital climate control panel, power windows, lighting etc.
The car absolutely takes off when the twin turbos come on boost, delivering that unmistakable 1980s "ketchup effect" turbo surge. The interior is in excellent condition, trimmed in light leather and Alcantara, and the car is completely rust-free, having been professionally rust-proofed when new by its first owner. The servo pump was not working when I bought the car, and I have not bothered to find a new pump since the steering is better for GT-trips with a more direct and sporty steering feel without the servo assistance. However, this also means that parking is a bit more heavy-duty for your upper arms.
All in all this is a rare opportunity to acquire an exceptionally well-preserved Biturbo Si that has been driven and maintained as intended. The car is located in Trondheim, Norway.
Over the past five years in my ownership, the car has performed beautifully and completely trouble-free. It has accompanied me on numerous road trips throughout the country, including the Gentlemen Drivers Weekend, the Maserati National Meeting, and various touring adventures with friends.
I have thoroughly enjoyed this car, but due to ongoing back problems over the past few years, I have come to realize that my collection of cars and motorbikes needs to be downsized. Everything I own is being used too little, and the key to keeping a Biturbo performing at its best is simply to drive it regularly.
My car has now passed 200, 000 km, but this is by no means unusual. I know of several Biturbos within the Biturbo community that have exceeded 350, 000 km. If a Biturbo Si is driven regularly, serviced properly, and the timing belt is replaced every three years while using the correct oil (Shell Helix Ultra Racing 10W-60), it will prove to be an exceptionally faithful touring companion.
The car comes with a binder full of invoices and service records, documenting its history and maintenance over the years.
As Classic & Sportscar wrote in the february 2026 issue: «There is undeniable charisma to the earlier Biturbos. The closest driving experience to a late 80s Biturbo is probably a Ford Sierra RS Cosworth, now worth many multiples of the Maserati. Biturbos have been bargains for most of their lives, but even with a recent upturn in prices as the market clamours for 1980s and 1990s cars, they are still incredible value”.
