okay pa rin naman iyun Chevy Optra ko, nakakatipid din ako sa cost of fuel. as for the resale value i honestly have no idea... with regards to your brother's opel astra, na phase out na kasi ng General Motors Ph. iyan brand and model, sayang maganda pa naman kotse iyan... with regards to parts, i think may available pa iyan sa Thunder which i can say is a lot cheaper compared to casa... doon na rin ako bumibili ng parts ko para sa Optra... and when it comes to service, direcho nalang sa servitec shaw para cheaper ang labor...
