 Mixed Conditional is formed by combining an if-clause from one type with the main clause from another:

                 (Type 2)                                         (Type 3)
                 if + past simple (past cont.)       would have + past participle

1. If I liked the singer, I would have come to the concert with you.
2. If I liked Chinese food, I would have gone to a Chinese restaurant with them.
3. If I were rich, I would have bought a Ferrari.

                 (Type 3)                                         (Type 2)
                 if + past perfect                         would + bare infinitive
