Marian was very hard-working and had a habit of spending as much time on training as he could so OBRSO (FSO Development Division) constructed special Polonez training car based on 3 door body with fiberglass parts like in 2000 Turbo but with much cheaper, modified 1.5 OHV engine and smaller dog-clutch gearbox instead of 2.0 DOHC turbocharged engine with more expensive transmission.

His new car was not ready to start in the first rally, so he rented the Patrick Snijers's Ford Sierra RS Cosworth 4x4 from ERC.

During the rally, 2 km from the start of the 5th special stage of Orłowiec – Złoty Stok, on 20 February 1993 his car came off the road at a right hand corner where he struck a tree.

Bublewicz in an interview said: "Many admirable rally drivers died, but I consider it as a mischance that can be quite quickly suffered by the loss of life in such discipline.

"[2] His death provoked a number of changes in safety and organisation standards on the rally special stages in Poland.

In a poll held by the monthly newspaper "Auto Moto i Sport" in 2000, Marian Bublewicz was named 'The Best Polish Rally Driver of the 20th Century'.
