Lyft has flirted with the idea of an acquisition, but a $6 billion offer from GM wasn’t enough to convince the company to sell, reports The Information. If it were to go through with an acquisition, Lyft is reportedly looking for $8 to $10 billion, an amount GM wasn’t willing to offer.

The transportation service has received acquisition offers from a number of companies, with the most important being GM, which invested $500 million in Lyft earlier in 2016. GM and Lyft are also working together on an autonomous vehicle fleet.

Lyft says it isn’t actively seeking a buyer, but it has at least received offers.
