I thought your budget would be somewhere between 14-15lacs, thats why I suggest you to get a Premio. You won't find a clean well-maintained Corolla X within your price range. In 11lacs you'll be able to get a '02-'03 Corolla X or a registered '05-'06 Belta. But if you increase your range to around 12 then I'd consider you to get a freshly cleared 1.0L Belta.
The Belta has been de-graded by majority of the PW'ers because they've been buying Corolla's for the past twenty years, majority of them haven't experienced the car nor have even drove one and yet they think the comments they give are from a professional point of view, which they're not.
