You absolutely need to get another independant shop to check it out for you. Find a shop that work on forein cars and is familiar and have them go over it for you. The dealer should have no problem with this if they are honest. They are fun cars and pretty reliable but can be expensive to work on in some cases so it is worthwhile to have it checked out first.
an you recommend a reliable shop/mechanic in that area ? If you know and recommend a certified mechanic that lives/works in or near glendale, CA I would be willing to pay for his/hers time and travel,
