However, the momentum did not continue. March had financial problems and a sponsor, Leyton House, acquired a controlling interest. Gugelmin finished third in his home race at Jacarepaguá in 1989, but this was done in the 1988 car. The definitive 1989 Leyton House March was a disappointment, and neither driver challenged for the top in the rest of the year. Capelli in particular only finished once throughout the season (12th in Belgium) and went far enough to be classified on one further occasion (Monaco where he dropped out from 6th place near the end and was classified 11th). Despite this, he was one of only six drivers to start in all of the 16 races of the 1989 season (the others were the McLaren drivers Ayrton Senna and Alain Prost, the Williams duo Riccardo Patrese and Thierry Boutsen, and Benetton's Alessandro Nannini). Team spirit remained intact despite the death of Gariboldi in a car crash and midway through the season Capelli felt happy enough in the team to take up his option for 1990. The new decade started poorly, though. Newey's car (given the prefix CG in honour of Gariboldi) had excellent aerodynamics and exclusive use of Judd's updated V8 engine, but it was intolerant of bumps. It was so bad on the notoriously bumpy Mexico City track that neither driver could control the car and both failed to qualify. Nevertheless, in the next at Paul Ricard in France came a complete turn around in form. Capelli led Gugelmin in a Leyton House 1–2 throughout much of the race. Gugelmin finally retired, and Capelli was overtaken near the end by the Ferrari of Prost with only 3 laps remaining and went on to finish second. Revisions to the car had made it more competitive (ironically Newey left the team shortly before the race to join Williams), but it was the billiard table-smooth track which allowed the result. Despite some promising showings at Silverstone and Hockenheim, it remained their best race of the season.
