BMW extended warranty for X5. Options?

[varun]

I am looking to extend the factory warranty of a 2004 4.8is, it is getting close to 50K miles. I will be the THIRD owner so some tell me I cannot get the 'original owner protection plan' which is basically the CPO warranty of 2 more years and 100k miles. At this point, what are my options? I want to get a BMW extended warranty only and not anything aftermarket. Where can I get this? BMW of Austin quoted me $4200 for the ORIGINAL OWNER PROTECTION PLAN which they say I am not eligible for. Any advice? Prices would be great too. MaconBMW is known to sell them at a good price, will check into that. Cheers!
