Help – Volvo V50 2.0 Diesel – good decision ?

Hello together, I have a little problem and hope for your support. After 4 VW Golf I would like to switch to Volvo and have already discovered a (as I find) nice car where I would like to have your opinion and experience. Volvo v50, 2.0 Diesel(136PS) EZ 06/2008, 55tkm Momentum, plus sliding roof, bluetooth Price: ~16t€ at a Volvo Hdl. I’ve already done a test drive and except for the somewhat hackly gearbox I’m totally thrilled! But have also heard that the immobilizer makes problems, it can come to gear damage, clutch damage. How your opinion? Is the Kauf worth it? Thank you and many greetings from NRW.
