lotuses use toyota engines for most of their models. they are good at the improving handling and some protons are actually pretty nice to drive, satria neo etc. just lacking in quality. preve improved a bit on that part though. it's not rebadging, it's using the platform. many carmakers share platforms. VW group for instance, alot of audi, skoda, VW, seat uses the same platform. Ford and volvo too, countless others. not a sin at all. i'm not a proton fan but if proton wants to improve i'm all for it, problem is, what's taking so long?
