It looks like to me that Sauber may be getting bought over by Honda long term. Longbow may have just scored a massive profit for a sell to Honda.
However, if Honda were to take over this entry, id bloody move it away from Hinwi as staffing there is taken up by a massive premium to attract the best staff to there, the only real alternative in that area of the world is Rebellion Racing, and they are a lean and mean team with only staffed with around 50 staff maximum. Sauber have almost 350 staff.
If i was Honda and i was to take over the Sauber entry, id bring in the dentist, Mr Kolles to run the team for the next two to three years at Hinwi, in that time id buy enough land, and build a big enough factory in the Cologne area or in the UK Motorsport Valley (Don't go to Caterham/Super Aguris old place, its been trashed and is cursed) so to get access to the German or UK knowledge base and get the team the access to the best staff.
Then for around 2019/2020 season, move the whole shooting match in to the new facility, Renault are now in the process of spending €220m in the factory and its facilities and infrastructure over 3 years in order to bring its chassis side up to par with Mercedes/Red Bull/Ferrari and other well funded teams. Honda would need to spend around €400m for a new factory and all its gibbons for the chassis side. In that time, if it was going to spend that dough, it would be able to bring its engine side up to par.
Too bloody many ifs and buts, but i could see it happening. As well as a 11th team for the 2018 season with cheap as Honda power.
