McLaren MP4-30

Information

Only raced once at 2015 Austrian Grand Prix. After the start, Ferrari's Kimi Räikkönen lost control and took out Fernando Alonso beside him. The two car smashed the barrier and the McLaren went on top of the Ferrari, with its floor almost hit Räikkönen's helmet. Both drivers were unharmed but their cars were heavily damaged. The MP4-30 and the SF15-T never raced again, presumably both written off.
Currently the MP4-30 is seen stored in McLaren Technology Centre with two MP4-30s still owned by McLaren, it's possible that it was repaired by McLaren.
