True about the equipment, with rover however is now being constructed by (from wikipedia)
The lead builder of the ExoMars rover, the British division of Airbus Defence and Space, began procuring critical components in March 2014. In December 2014, ESA member states approved the funding for the rover, to be sent on the second launch in 2018, but insufficient funds had already started to threaten a launch delay until 2020. The wheels and suspension system are paid by the Canadian Space Agency and are being manufactured by MDA Corporation in Canada.
The areas that seemed to have failed on the lander were not Russian, the only Russian mission to Mars I think was more botched than bad luck was Mars '96, not built and launched at the best time for the Russian space program.
If there was a weakness with the USSR probes in the Cold War it was with electronics, witness the fate of the probes launched in the window after the 1971 missions that hit the dust storm, distances are further, compared to Venus, so longer flights where these weaknesses were compounded.
These don't exist today.
True Russia has never done an Outer Planets mission, I'd like to see them have another crack at landing on Venus, with today's technology and the robust heritage of the Venera missions.
