Suprise to see the mark x also on the ts list. If it is a recond model, do allocate some budget to change all wear n tear parts as well, especially the tyre, absorber, that engine mounting (which all of this can cost few thousand for parts n install). Then normal engine servicing with gb oil change. Since it is toyota, expect it to be reliable for use.
Suprima is on of the best looking proton car, especially compared it to preve and other proton model. Just that the CVT with clutch based might not jerking free on daily use. To be save better get suprima with under warranty as I see many Preve (same brand punch GB) had a cvt gb replacement under warranty. As i experienced on my office suprima, its FC is kinda high side, i can say my honda 2.4 have a better fc for daily working use (city jam around KL to Kajang back & forth daily)
Other than that, the HU on my office car is always hang n restart by itself especially when using gps on it.
