Switch S60 2.4i to V50 T5

Hello, I’m about to change from my S60 to a V50 T5 BJ 2005. The car has a previous owner, was waiting every year at Volvo and has 100,000km on the clock. Would buy it from the friendly Volvo dealer with new inspection. The car makes a solid impression. What call do I have to pay attention, or what are the typical flaws, flaws in the car? Are the inspection costs and spare parts prices on the V50 T5 higher than on my S60 2.4i or does that hold the balance?
