Hi All, I purchased an 03 Corolla Sportivo yesterday and paid in full :D It's a dream I had for years, so I was very happy. Until I noticed the engine light go one, you know the one in the manual which says, 'take to dealer immediately'. So I range the bloke I bought it off - he said that the light had been on for 6 mths, he took it to the Skyfleet Kedron and they said it wasn't a critical issue, that it would be 100ish to fix. He told me to go there and check if I wanted. I didn't notice this light during test drive btw, stupid I know. So I rang them, and yes, they had his (mine now, hehe) corolla on their system and mentioned the Oxygen sensor unit. Said it wasn't urgent but should be fixed to improve performance, and quoted me almost 400. 300 for the part and 100 for the install. My question is: Should the safety certificate have picked this up? Or does this not matter for a safety cert? Is there anywhere cheaper or should I get it done at Toyota? I rang Repco and they said they didn't have the part for the tivo model no :( What should I do? Is it necessary to fix this immediately? Obviously the ex-owner doesn't care because he has his money, but its kinda dented my tivo buying experience. It seems lowering will have to wait sigh lol. Thanks for you help guys, Jus
