Mate., I have been driving a multitude of vehicles for the last 10+ years.. so trust me., I have enough experience when it comes to this matter.
My first car was a second hand and ...damn... it made me sick with all the maintenance, spare parts etc etc... so from that moment onward i stopped buying second hand vehicles all together.
Even when I buy a Japanese., I just make sure it's brand new and I only keep it for Maximum of 2 years with me and sell it off. But for the last couple of years., I have been buying these Korean and Chinese vehicles given that they are pretty much a comfy ride and bloody well cheaper.
so., just buy it.. use it.. and sell it ==> end of headaches and problems !
